Several Grapefruit League teams had reportedly first planned to honor victims by wearing the school's caps before their league openers, but Commissioner Rob Manfred said that within 48 hours all 30 teams were confirmed to wear the hats during pregame warm-ups for their exhibition openers.

Players, managers, coaches and umpires also had the option to wear the hats during the games.

Tampa Bay Rays first baseman Brad Miller told ABC Action News it was the right thing to do.

"Devastating thing, a tragedy," Miller said. "And, obviously the Florida community Anthony Rizzo, I know that’s his alma mater, so somebody in the baseball family. I think everyone has some sort of connection down there. It’s something small but wearing these caps bringing some awareness you helping these families whatever we can do."
